SPECIFICATION forming part of Letters Patent No. 636,606, dated November7, 1899. Application filed ilune 15, 1899- Serial No. 720,716. (Nomodel.)

T0 at whom it may concern/.-

Be it known that I, ALEXANDER WINTON, a citizen of the United States,residing at Cleveland, in the county of Ouyahoga and State of Ohio, haveinvented new and useful Improvements in Explosive-Engines, of which thefollowing is a specification.

My invention relates to improvements in explosive-engines, and pertainsto an engine which is particularly adapted and intended for use inconnection with a motor-carriage.

In motors for carriages it is exceedingly advantageous to have asmooth-running and well-balanced engine to prevent unpleasant jarring tothe body of the vehicle and to decrease the wear and tear upon themachine, and consequently lessen the liability of injury thereto andincreasing the life of the engine and its cooperating mechanism.

With these ends in view the primary object of my present invention is toprovide a balance -weight for the piston and crank: which moves inopposition to the said piston and crank, and to further increase theutility and effectiveness of the said balance-weight by connecting itwith a pump.

In the accompanying drawings, Figure 1 is a perspective view of anengine embodying my invention, partly shown in section and partly indotted lines. Fig. 2 is a detached View of the eccentric andbalance-weight connecting-rod.

Referring now to the drawings, A indicates a casinginclosing anengine-cylinder B, which is of the usual construction or of other formas desired.

0 is the piston, D the crank-shaft, and E the pitman, which is connectedat one end with the piston O and at its opposite end with the crankwrist-pin F.

The explosive end of the cylinder is provided with an explosive-inletclosed by the explosive-inlet valve G, which is provided with a stem H,projecting through a cylinder 1. This cylinder I is'provided with adividing web or plate J, and through which the stem H also passes.Secured to the outer end of the stem H is a piston or diaphragm K, andcommunicating with the space between the piston K and the dividing webor plate J is an air-pipe L. This pipe L is in communication with anair-pump cylinder M through the medium of a pipe N, whereby air ispumped into the cylinder I for holding the inlet-port valve Gr closed,and the amount of pressure within this cylinder regulates the amount oftension upon the inlet-port valve, and thereby the amount of chargeadmitted to the explosioncylinder. The pump-piston P has its end Qextended and passes through a bearing R, the said bearing beingsupported by the bracket S extending from the casing A, thus furnishinga space between the bearing R and the casing.

Secured to or formed as a part of the extension of the pump-piston P,and thereby practically upon the piston, is a balance-weight a. Thisbalance-weight a is connected by means of-the eccentric pitman b withthe eccentric-strap c, which passes around an eccentric d,secured to thedrive-shaft E. It will be noted that the eccentric d is positioned uponthe drive-shaft E in opposition to the Wrist-pin F, so that in theoperation of the engine the pump-piston, and consequently thebalanceweight a, are moving in the opposite direction of the movement ofthe engine-piston O and the engine-pitman E, and serves to balance theseelements. The eccentric pitman 'b is bifurcated and provided with thetwo parallel arms e, which are connected to opposite sides of thebalance-Weight a for the purpose of preventing any lateral thrust uponthe pump-piston and to cause a direct pull thereupon. The ends of thesearms e are connected with the balance-weight a by means of suitable pinsor bearings f, projecting from opposite sides of the said weight.

The advantage of having the weight connection with the pump piston istwofold. First, the connection of the weight with the pump-pistonenables the piston to furnish a yielding resistance to the movement ofthe weight, thus preventing the sudden stopping and starting of theweight, which would otherwise occur, and causes the pump to perform thedouble function of a pump and of a dash-pot, so to speak,for effectingthe movement of the weight. Another advantage of the said constructionin connection with a motor-carriage is the saving in space and also acheapness in construction in that the pumppiston serves as a support forthe weight as well as a piston for the pump. Attention is also directedto the fact that this weight is a vertically-disposed weight and extendstransversely in respect to the said piston, and thereby parallel withthe side of the casing A, which specific construction also is an economyin space.

For the purpose of regulating the amount of air-pressure against theinlet-port valve G, I provide an escape-regulating mechanism connectedwith the pipe L through the medium of a pipe g. This escape mechanismconsists of an escape-valve h, which is set to regulate the pressureupon the inlet port valve G to a fixed pressure, whereby the engine willrun at a fixed rate of speed, and for the purpose of relieving thepressure upon the said inlet-port valve G, and thereby increasing theamount of charge and the speed of the engine, I provide a foot-valve e,having an escapej. The escapes of the valvesi and h are in communicationwith a single escape-opening 7c, the escape of the valve 7t beingconnected with the said escape 7.; through the medium of a pipe 70. Theadvantage of this construction is to provide only a single escape forthe air, and thereby reducing the noise as compared with a single escapefor each of the valves 7L and t'.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. An engine comprising a cylinder, an inlet-port therefor, aninlet-port valve, a pressure-regulating member connected with theinlet-port valve, a pump in communication with the pressure-regulatingmember, a driveshaft, a pitman connected with the driveshaft and withthe engine-piston, a piston for said pump, a weight connected with thepiston, the drive-shaft havinga crank or eccentric arranged inopposition to the pitman,and the connection between the crank oreccentric and the pump-piston and thereby the balance-weight,substantially as described.

2. An engine comprising a cylinder, a piston, an inlet-port, aninlet-port valve,the pressure-regulating member connected with theinlet-port valve, a crank-shaft, a pitman conlet-port,apressure-actuated member connected with the said inlet-port valve, apump in communication with the pressure-regulated member, a piston forsaid pump having an extension, a bearing for the extension of saidpiston, a balance-weight connected with the pump-piston between thebearing and the pump, and a connection between the eccentric and thebalance-weight, substantially as described.

4. An engine comprising a cylinder, a piston therein,a crank-shaft,apitman connecting the piston and the crank, an eccentric upon the shaftin opposition to the said crank, the cylinder having an inlet-portvalve, a valve for said port, a pressure-actuated member connected withsaid valve, a pump in communication with the pressure-actuated member, apiston for said pump having an extension an d a vertically-disposedbalance-weight secured to the pump-piston, and a connection between theweight and said eccentric, substantially as described.

5.

6. An engine comprising a casing, a cylinder within the casing, a pistonwithin the cylinder, a crank-shaft, a pitman connected with thepiston-cylinder and with the crank-shaft, an eccentric disposed upon theshaft in opposition to the crank, the cylinder having an inlet-port, avalve therefor, a pressure-actuated member connected with the valve, apump in communication with the pressureactuatcd member, a piston forsaid pump, a balance-weight secured to the piston and arranged parallelwith the sidcs of the said casing, and a connection between theeccentric and the pump-piston, substantially as described.
